special function

Terminal Delay

Switch input and output terminals can be set with response delay (0.0~6553.5s).

Jog Control

Control method: terminal, communication

Frequency: 0.00Hz~ maximum frequency; acceleration and deceleration time: 0.0~6500.0s

Multi-speed
Simple PLC

Up to 7 speeds can be achieved through built-in simple PLC or switching input terminals.

Built-in Two Sets of PID

When used as an ordinary PID, it can easily realize a closed-loop process control system.

Fixed Length, Counting

Pulse signals (0 - 50kHz) can be counted and matched with switching output terminals to achieve counting arrival control; the count value can also be converted into length for display and fixed length control.

Anti-swing Frequency Control

It can realize constant swing amplitude, constant mutation and constant period output at any frequency.

Timing Control

Timing controllable (0.0Min~6500.0Min)

Momentary Power Loss Ride-Through

When there is an instantaneous power outage, the frequency is reduced to reduce the load feedback energy compensation bus voltage, thereby maintaining the inverter from stopping for a short time.

Peripheral Terminals
